Create a calculator using Angular [angular]

#Angular Calculator

Your goal is to create a calculator using Angular. Starter code has been provided for you.

Getting Started

• Fork and clone this repository
• Run npm install to install dependencies
  • npm start to run the BrowserSync server
  • npm run lint:js to lint your JS
  • npm run lint:css to lint your CSS

The calculator should function as follows:

• Calculator should start with a 0 value
• If a number is pressed it should overwrite the 0 with that number
• If a subsequent number is pressed it should be appended to the end
• When pressing an operator (+, -, x, ÷) there should be no apparent change.
• When entering a new number the screen should clear and be replaced by that new number
• Again, each subsequent number should be appended.
• When another operator (or equal) is pressed it should total the values and update the screen (and be ready for the next operation)
• If a number is entered without an operator being pressed first it should clear the screen / memory and that new number should become the running total
• Pressing clear should revert it back to 0

For an example of how the calculator should function see the built in OSX calculator (go to spotlight search CMD+SPACE, "calculator", and hit enter)

##Suggested Process

• Add ng-app / module (test with console.log)
• Add ng-controller / controller (test with console.log)
• Bind display to $scope variable
• Get buttons to update display
• Get clear button to clear display
• Work on getting operators working

##Bonuses

• Highlight the active operator key using ng-class
• Add decimal point button
• Add a positive / negative button
• Add memory / recall buttons
